In this paper, we give an analogous description of the algebraic closure of the fraction field of the Witt ring of a field of characteristic p, using an analogue of generalized power series in mixed characteristic due to Poonen.12 pages; uses AMSLaTeX and xypic for one figure (replaced 16 Dec 1999: corrected proof of Theorem 1)Algebraic GeometryCommutative AlgebraRings and Algebras12F05 (Primary) 14Q05 (Secondary)text
